Splet26. sep. 2024 · In this study, the shrinkage and creep of concrete containing graphene oxide (GO) nanosheets were experimentally and theoretically investigated. Experiments for the shrinkage and creep of concrete with 0.02% and 0.08% GO nanosheets by the weight of cement and common concrete were carried out. Subseq … Splet19. jan. 2024 · In normal concretes, most of shrinkage represents the drying shrinkage, which is caused mainly by increase of the capillary tension of pore water and the solid surface tension of pore walls, as well as thinning of multimolecular hindered adsorbed water layers in cement gel micropores.
